Abstract

•The novel Schiff base derivative of calix[4]arene was synthesized in the present study.•The Schiff base derivative of calix[4]arene was characterized using spectroscopic techniques.•This compound was examined for its fluorescent properties towards different metal ions and anions.

A new pyrene-based calix[4]arene was synthesized. This compound (4) was examined for its fluorescent properties towards different metal ions (Mg2+, Ni2+, Ba2+, Ca2+, Cu2+, Pb2+, Zn2+) and anions (F−, Cl−, Br−, H2PO4-, NO3-, HSO4-, CH3COO−) by UV, NMR and fluorescence spectroscopy. Fluorescence spectroscopy demonstrated that 4 exhibited high affinity for Cu2+ and low affinity for Pb2+, Mg2+, F−. Quenching constant and stability constants for complexation of 4 with Cu2+ and F− have been determined according to literature.
